LUBRICATOR FOR STEAM IJIAUHINERY.

T 0 all whom it may concern:

Be it known that I, GEORGE W. Enwrinns, a citizen of the United States, residing at Menasha, in the county of VJinnebago, State of Wisconsin, have invented certain new and useful Improvements in Lubricators for Steam Machinery and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and usefu improvements in lubricators for steam machinery.

The object of my invention is, to provide a lubricator in which the action of the water and oil may be observed, and which is so con structed that the lubricant as it travels through the glass feed tube will be guided along a conducting wire, held within a suitable sleeve, to prevent the glass feeding tube from becoming befouled or tarnished by the oil.

In the accompanying drawings I have shown in Figure 1 a sectional elevation of a lubricator embodying my invention, and Fig. 2 shows an enlarged detached detail of the guiding tube in section.

In certain classes of steam machinei' r a lubricant is automatically fed to the working parts of the machinery, by the action of the steam and water. In these machines it is highly desirable that the lubricator by means of which the oil is automatically distributed, be so constructed that the quantity of oil feeding from the reservoir may be seen at all times so that the flow of oil can be properly gaged.

Referring by numerals to the accompanying drawings 2 represents a hand-valve casing connected by means of thetube 1 to a suitable reservoir 5. This hand valve casing is provided with the seating 3 against which the end of the valve stem 4 abuts. This valve stem is operated by means of the hand wheel 6. Secured to this hand valve casing 2 is a feeding nipple 7 and surrounding this feeding nipple is the glass tube 9 secured by means of the packing ring 10. This tube 9 is extended upward into the union 12 the tube being secured by the packing ring 13. This union has an intake port 14 and an exit Specification of Letters Patent.

Application filed March 27, 1968.

Patented May 18, 1909.

Serial No. 423,737.

1 port 15 the steam and water pipe 16 enter- I ing the intake, while the tube 17 is projected from the exit port 15. Above, this union 12 |is provided with the threaded opening 19 I within which is held the plug 20 and held within this plug 20 is the metal guide tube I 21 which ends a suitable distance above the l J l l l l nipple 7.

Held centrally within the plug 20 is the pendent conducting wire 23 which terminates proximal to the exit opening of the nipple 7. Upon the lower end of the wire 23 is provided a metallic conoidal plug 23 which is so positioned as to close or partially close the opening in the feed nipple 7 when r the wire 23 expands; Furthermore, this part 23 insures the drops of oil, passing up from the nipple 7, coming in contact therewith and flowing properly along the wire 23 l as hereinafter explained. In referring to Fig. 1 it will be noted that the guiding tube is of a length less than the conducting wire 23.

vided with the discharge openin is directed into the discharge port 15.

The tube 9 forms an observation tube so 1 that the exact amount of oil escaping out of l the nipple 7 may be noted. l The operation of the lubricator is very simple. The steam and water enters the lunion 12 through the pipe 16 and circles r about the conducting tube 21 finding an escape through the pipe 17. The valve stem I I will in the meantime have been adjusted l The tube 21 near its upper end is prowhich to permit the desired amount of oil to escape through the nipple 7. Now this oil escapes in drops and as it leaves the nipple encounters the conducting wire immediately above the nipple along which it glides until it is stopped within the upper end of the guiding tube 23 from which it is drawn by the out rushing steam and water. By this means the oil will be prevented from coming into contact with the observation tube 9.

The device is simple of construction and may be readily operated, and

Having thus described my said invention what I claim and desire to secure by U. S. Letters Patent is A device of the character described, having in combination, a valve casing, a feed nipple extending from said valve casing, a

glass tube secured to said Valve casing, a I opening, all arranged substantially as and union having suitable intake and eXit ports secured to said tube, a conducting wire pendent from said union and having its lower end proximal to said nipple, and a guiding tube secured to said union and surrounding said wire of a length less than said wire and provided with a lateral discharge for the purpose set forth. 10

In testimony whereof, I aifix iny signature, in presence of two witnesses.
